I'm trying to find a diamond hole bit that will allow a hole large enough for a 1" bulkhead. The company I'm looking at carries 42mm. Is that too small?

I believe that's too small.

I just got a couple 45mm from glasshokes. BRS sells them, too.

Yep, jcw has it right, you need either 1.75" or 45mm.

agree with both the above. 45mm is what you need.
